This mixer module achieves up and down conversion function within the frequency range of 5-21GHz, with a maximum frequency of up to 21GHz. This module adopts a CNC structure shell, which has good electromagnetic shielding performance.<br> The module uses a high-frequency low insertion loss circuit board, with LO/RF operating in the broadband range of 5-21GHz and IF covering DC-5000MHz. It is applied to typical frequencies such as 5.8G, 8G, 12G, and 18G, achieving up and down conversion function. Widely used in corresponding frequency band ceiver systems, its small structure is easy to install and use.<br> Typical Use and Features:<br> RF mitter up conversion<br> RF receiver down conversion<br> Low frequency conversion loss<br> CNC structural shell<br> SMA standard connectors<br> Specification:<br> Model: QM-MIX0521S<br> RF/LO working frequency: 5 - 21GHz<br> IF intermediate frequency operating frequency: DC-5000MHz<br> Frequency conversion loss: 8 - 12dB<br> Isolation degree: LO-RF: 29dB (typ.)<br> LO drive of local oscillator: +15dBm<br> Input/output interface: SMA-K<br> Size: 34 x 20 x 11mm (excluding connector length)<br> Instruction:<br> RF input: RF port<br> Local oscillator input: LO port<br> Intermediate frequency output: IF port<br> RF/IF port maximum input: +21dBm<br> Due to different product batches, the appearance may vary, which does not affect the use.<br> Colour:As Shown<br> Material:aluminum alloy+PC<br> Package Contents:<br> 1 x RF Frequency Mixer<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
